B2. You've been provided with the following data, covering one year, concerning the portfolios of two equity managers (manager A and manager B). Although the portfolios consist primarily of common stocks, cash reserves are included in the calculation of both portfolio betas and performance.

Total return Beta Manager A 24.0% 1.0 Manager B 30.0 1.5 S&P 500 21.0 Lehman bond index 31.0 91-day Treasury bills 12.0 a. First calculate the alphas and Treynor ratios of the two managers and then compare the risk adjusted performance of these two managers relative to each other and to the S&P500. b. Explain why the conclusions drawn from this calculation may be misleading
